Already have a copy of that - it's the actual copy of the original Cyrillic Technical Book I'm after for the parts lists !

Hi!

A helpful Member sent me a full German Manual and I found a full Cyrillic one after a few days searching on a Russian radio forum, so work on a brand–new full English Technical Manual has now been started!

The last page of the manual illustrates the two special tools that need to be manufactured for the collet knob fixings, and I attach my new drawings for them here!

First two new circuit sheets giving Block Diagrams in English also added!

PS!

I missed off a link from the "Sign Trigger" block to the "Digit Unblanking Pulse Shaping" block in the second page of the "Circuit Diagram Sheets 1 and 2" attachment - I've now corrected and re-uploaded it!

Hi!

Circuit Diagram in English, Sheet 3, PCB Unit 1, Sync, Trigger, T.B. and X Amplifier for the C1-112A Oscilloscope!

Original Soviet–era circuit diagrams unfortunately do look very much like somebody has vomited all the сomonent symbols all over the page with no thought as to how to lay them out in a functional and workable manner, and I hope that my replacement diagrams fit the bill a little better in this respect!

Chris Williams

PS!

Diagram updated with minor corrections, additional notes and symbol details - please use this one for all future work!

I have this Soviet/Russian-made school-laboratory oscilloscope which is supposed to be used as “teaching aid in high schools and radio-amateur practice”. The model is H3017 (N3017) and was manufactured in 1990. Based on a poorly translated Instructions Manual it appears to be a 100 kHz scope (amplitude non-uniformity, referenced to 1 kHz: (i) 0-100 kHz +/-30%; (ii) 100-500 kHz +/-65%). The time base and y-channel amplitude potentiometers for fine adjustments are not calibrated/graduated, so accurate voltage and frequency measurements could not be performed with this scope. Only waveform shapes can be visualized.

The text-only translated Instructions Manual makes reference to block and schematic diagrams for this scope but I don’t have the original manual in Russian. I need to get a 120-230V step-up transformer before I could test the scope to see if it still works.

Does anyone have information about this model? Or, would anyone have access to the original Instructions Manual in Russian, including the diagrams?

Thanks!
